Abstract

High-purity gas purifiers for purification of corrosive gases, such as halogen gases or halide gases, and noncorrosive gases, such as hydrogen and inert gases, methods of making and methods of using the gas purifiers, are described. The gas purifier includes a housing made of nickel or stainless steel. Within the housing, the gas purifier includes a purifier resin, including a modifi-er coated onto a substrate. The gas purifier further includes porous nickel membranes located at the inlets and outlets of the device. The inlets and outlets are capable of fluid communication with external fixtures.

Claims (11)

1. A method comprising, generating a media for a gas purifier by coating at least a portion of a porous support with a metal halide solution, drying the coated porous support to form a metal halide coated porous support, and conditioning the coated porous support with a purified hydrogen halide gas.

2. A method according to claim 1 , further comprising activating the metal halide coating.

3. A method according to claim 2 , wherein activating comprises heating the metal halide coating.

4. A method according to claim 3 , wherein activating and conditioning occur at the same time.

5. A method according to claim 1 , further comprising placing the coated porous support into a nickel shell to form a gas purifier.

6. A method according to claim 5 , wherein drying occurs after placing the coated porous support into the nickel shell.

7. A method according to claim 1 , wherein the porous support is a porous carbon or porous alumina.

8. A method according to claim 1 , wherein the metal halide coating is a Group I or Group II halide salt.

9. A method according to claim 1 , wherein the coating is a fluoride salt.

10. A method according to claim 1 , further comprising flowing nitrogen gas over the coated porous support during heating.

11. A method according to claim 5 , wherein the nickel shell includes two or more different coated porous supports.
